With my Garmin there has always been a problem when connecting to a car that the car rather than just giving power to the device would try to connect. This eliminates that problem. Now with rental cars I've switched to Google Navigation and I like that this isolates power only to your usb device, and that way my phone is safe from a USB Virus attack from a rental car. The peace of mind of being able to plug into any USB JACK and just get power only is priceless. CONS: These are easy to loose either to theft or just putting in a drawer and forgetting which one. Yes I'd buy these again, and just did as didn't want to spend time looking, Also I'd recommend them to friends. bdv Review: Great Tool for Finnicky USB Devices (old Garmins) and Defeating Fast Charge Protocols - Great for devices that will freak out or change modes when they detect *any* data communication -- the red one has a charge protocol detection chip which is useful when securely charging high-draw modern devices, but useless for diagnostic purposes or legacy devices. This adapter is a fantastic way to use standard mini USB leads with devices running the older GarminOS based on an unknown embedded OS (used as recently as the DriveSmart 50, many still run current maps with a microSD setup). These devices give no choice to simply charge if a data connection is detected and block out the UI in PC Connection mode. Newer Linux-based ones (like DriveSmart 65) now have a prompt and will work as expected with the red adapter in a secure charging scenario, or bare lead for normal use. Since USB-A luckily tops out at 2.4A under most cases, even the red one will charge modern devices at a sane rate, but for devices with low standby draw that can trickle charge at 500mA this is useful to defeat fast charging protocols for debugging or increased battery life. The red one should still be safe even if your device uses Qualcomm BatteryKiller 3.0 because of it visibly having no upstream data pins to the charger required to enable fast-charge combinations that are unacceptable for everyday use. In this context this (clear) one is good if you're paranoid, or it's a rare device where the 5v@2.4A provided by the USB BC 1.2 standard is too much . ## Features - Attach between your USB cable and charger to physically block data transfer / syncing; Charge mobile devices without any pop-ups or risk of hacking / uploading viruses in cars, airports etc - The only data blocker to physically show you that its blocking data and several other great features; See full details below - Attach between your USB cable and charger to physically block data transfer / syncing; Charge mobile devices without any risk of hacking / uploading viruses in cars, airports etc ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07J6QFZ4V | | Best Sellers Rank | #985 in USB Cables | | Brand | PortaPow | | Built-In Media | Data Blocker | | Color | White | | Compatible Devices | Smartphone | | Connector Type | USB Type A | | Customer Reviews | 4.6 out of 5 stars 8,250 Reviews | | Item Package Quantity | 1 | | Manufacturer | PortaPow | | Mfr Part Number | PPUSBDBW2 | | Model Number | PPUSBDBW2 | | Number of Items | 2 | | Number of Ports | 2 | | Package Quantity | 1 | | UPC | 027829469382 | | Unit Count | 2 Count | | Warranty Description | 2 Year Manufacturer | ## Product Details - **Brand:** PortaPow - **Color:** White - **Compatible Devices:** Smartphone - **Connector Type:** USB Type A - **Number of Ports:** 2 ## Images ![PortaPow USB Data Blocker (White 2 Pack) - Protect Against Juice Jacking - Image 1](https://m.media-amazon.com/images/I/61AKj7LdoqL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Can anyone confirm 100% that this will allow an iphone to charge off a usb port without having the iphone driver installed.** A: Its a data block... 100% NO USB DATA CONNECTION! So absolutely no need for a any data modifications on the USB host... **Q: I’m having an issue with no sound coming from my phone when I charge it in the car from the USB port. I read somewhere that this might help. Yes?** A: If the problem is that you're plugging your phone into your car to charge, and your phone is detecting your car as an "audio out", then it is at least *possible* that this may solve your problem. But even some devices can detect that "something is plugged in" even if the data port is blocked. A better solution is to figure out how to change the audio device on your phone. If it's android, you can select "charge only" when plugging into USB. Ultimately, even if this device doesn't solve your problem, it's still helpful to have as a security device. **Q: does this actually block data from being sucked from your iphone and/or from data/virus being inserted into iphone? does it also chagre?** A: That's what it's supposed to do, yes. I bought it to be able to charge an old iphone from a VW Jetta USB port that was not compatible with the phone and it works fine for that. As far as I can see, it basically passes through the 5v connections and has no data connections so there would be no way a virus could be passed through it or data could be "sucked" out. Of course it also means you can't download photos or sync your phone or anything like that - all it does is let you charge. So, basically, it turns a computer USB port into a non-smart charger. That also means it charges slowly at 0.5A whatever the port or charger rating, because higher charge rates are negotiated between charger and phone, which requires data. **Q: Does this work with iPhone 8 and 11?** A: Yes. This has worked with all of my phones for the past 4 years including my current iPhone 11 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple and Works no Juice Jacking here ;) bdv *by W***E on February 25, 2025* Pros: I like the price and fact that the red makes these stand out.

Yet you must avoid overexpecting. USB charging has become a surprisingly complex situation over the years, with various only partially-compatible standards vying for prominence. Given the complexity, the PortaPow manages to likely provide a.) charging instead of nothing and b.) for advanced devices sporting high-rate charge capability, some charge rate _between_ the maximum the device would negotiate with a compatible charger and the mere 500 mA of original USB. To check the above, I selected a Quick Charge 2.0 compatible phone for which I already had various charge rate data and compared those data to observations using the PortaPow Data Blocker. With the phone starting somewhat below half charge, charge rates via a PortaPow Data Blocker from a "Smart 2.4 A" USB port and a Quick Charge 3.0 port were a bit below and a bit above 30 %pt/hr (percentage points per hour), respectively. Good, but of course less than the 56 %pt/hr I've observed with direct connection to a Quick Charge 2.0 charger. Charge rate through the PortaPow data blocker proved similar to wireless charging of the same phone. For another view, I collected a range of Garmin GPS units and observed simple usability. Garmin Nuvi models tend to switch to data transfer mode when connected to anything that seems unlike a Garmin power cable. This prevents user operation unless one works around that tendency (some models will time out and restart in operation mode, the simplest workaround). With the PortaPow data blocker between a notebook computer and each Garmin, only the oldest, a Nuvi 200W, switched to data transfer mode; all the later models I checked simply continued operating as usual. So, if you want a handy way to operate your Garmin Nuvi GPS from external power without being in a vehicle, the PortaPow data blocker may do the job without the bulk of an additional Garmin-specific charger. You'll lack traffic reception, of course, unless using a smartphone for that. Charging performance of Garmin Nuvi models through a Portapow Data Blocker may be more interesting. Recent models reported "Suspend" or "Unknown" as their input current limit setting, while an older model reported 1 A. Starting near half charge and operating your individual unit for a while via a PortaPow Data Blocker would be the way to assess whether it charges (adequately) or at least doesn't discharge while you're operating it. ## Frequently Bought Together - PortaPow 3rd Gen USB Data Blocker (White 2 Pack) - Protect Against Juice Jacking - Zpsolution Zipper Clip Theft Detterent - Keep The Zipper Closed - Zipper Pull Replacement - LHJRY Multi Charging Cable (3Pack,4ft) 6 in 1 USB A/C to USB C/Micro USB/i-P Connector Multiple Charger Cord for Cell Phone/IP/Galaxy/PS/iPads and More --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/94220406-portapow-usb-data-blocker-white-2-pack-protect-against-juice](https://www.desertcart.be/products/94220406-portapow-usb-data-blocker-white-2-pack-protect-against-juice) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-22*
